but I don't get why my ISP recently started blocking those ports. I found a thread that said they were blocked, and that they soon will be unblocked, but I have yet to find out why the change.

Aha!
Security Now podcast ~397 says that Shields Up port scan is now reporting if there is any response from the port at all (on various protocols) and not just a port closed message from me. My ISP is blocking these ports and publicising it, and always has been. GRC now detects this blocking, whereas previously it didn't. That explains it.
